This 5-star review is for the solid-color pants. They are like wearing clouds, the most comfortable thing I've ever worn. It is very true that one should order a full size down from what you usually wear, which is what I did and got Small. I also ordered the Turtle print pants and returned them. I'm not sure why the construction in the print pants is different, but the fabric is a bit stiffer (relatively; it's still soft) and the pants appear to be lined, making them heavier than the solid colors. I returned the Turtle pants even though I loved the look, for that reason; they just weren't the same as the solid color ones. Solids are 95% modal; the description doesn't say what the print pants are made of.
